faluco f0d651ae8e - Fixed a leak in the MME class not releasing the static byte buffer pool.
- Now the pool gets destroyed on program exit using a unique_ptr.
- Removed manual cleanup() calls in all the code base to free the pool instance.

Andre Puschmann eeb2b904aa ue,rach: fix failing RACH proc when Msg3 grant RNTI matches current CRNTI
this was preventing that the Temp-CRNTI used in the RAR to be identical
to the currently configured C-RNTI of the UE.

The issue simply was that the RACH procedure was declared successful too
early, even before the Msg3 UL grant was filled with the Msg3 content.

The patch moves the logic that detects the successful completion of
the RACH procedure below the Msg3 packing.

Andre Puschmann b616944a13 ue,rrc: fix security config during HO/reestablishment
we fix a number of very related issues for HO/reestablishment
in the success/error case:

* this patch removes the hard-coded check that intra-cell HO aren't
allowed. There are cases where eNBs use this method to update
the security context.

* the patch also fixes an issue after failed HO where the security context
of the source eNB should be used for the reestablishment.

* update security keys according to specs when mobilitycontrol
indicated change of key

Andre Puschmann 6827c2df21 rrc_meas: disable layer3 filtering until quantity config is received
the filter alpha was initialized to zero by default which causes an
issue because the first measurement for a cell can't be updated,
because the filtering function will always return the current value.

According to 36.331 Sec 5.5.3.2 Note 2, a k-value of 0 should turn
off filtering, which should be used as the default value until
an update is received from the network.

Francisco Paisana 97133894e6 the Ocs value used in the measReport triggering decision was not being set correctly. The enum of the cell individual offset in the measCfg was being cast to an int and stored. Instead what we want is to store the actual offset value using the ASN1 enum->number lookup table. 4 years ago

Andre Puschmann 624c8142ad ttcn3: refactor cell handling in SS
this rather large patch changes the way cells are handled in the SS.
It moves RLC and PDCP entities to the cell map of the SS, such that each cell
has its own entities. This allows to support HO operation, for example,
in which two cells need to send SRB messages.

It also extends most of the syssim interface to include the cell name
in all commands so they can be applied on the specified cell only.

Andre Puschmann c16ac6c890 ue_stack: only push sync event to event queue is stack is still running
stopping the UE in ZMQ mode caused a dead-lock because the Stack was
stopped before the PHY causing the sync queue to overflow. Since we
use a queue-length of 1 in ZMQ, mode, the PHY sync thread was blocking to
push a new sync event while the stack thread was already stopped.

this patch makes sure no new sync events are queued after the stack has
been terminated.

Andre Puschmann aec18a93d1 mux,bsr: refactor UL buffer status reporting
this patch fixes the UL BSR as per TS 36.321, it includes following
main changes:

* report UL buffer state to reflect the UEs transmit buffer after
  the MAC UL PDU containing the BSR has been built.
  In other words, if the UE, for example, can transmit all outstanding
  data in an UL grant, it will not report any pending data to transmit.

* refactor MUX routines and subheader space calculation

Andre Puschmann 6364a4513c mac_pdu: fix issue when packing CE but no space left in PDU
we've not checked the return value when adding a new CE, like BSR or PHR,
for a UL MAC PDU. For very small UL grants, this could fail and
we need to remove the subheader again before packing the PDU.

This fixes issue #1649.
